How to deploy Etherpad Lite on Cloudfoundry.com

In case you're not familiar with Cloud Foundry, it's an opensource platform as a service (PaaS) project sponsored by VMware. https://github.com/cloudfoundry

Get etherpad code with cf support: git clone git://github.com/rozcietrzewiacz/etherpad-lite.git; cd etherpad-lite
Install node, npm and other dependencies as usual.
Copy/rename settings.json.template to settings.json and adjust the settings to your liking.

Create a MySQL service (replace myDatabase with a name of your choice) : vmc create-service mysql myDatabase
[crucial step] Make sure you're in the etherpad-lite folder and upload your Etherpad to the cloud with (replace myEtherpad with any name you want) : vmc push myEtherpad --mem=128 --runtime node06. You'll be asked a few questions at this point - for most of them, you can just press Enter, but make sure to answer y to the following two:
Would you like to bind any services to 'myEtherpad'?
Would you like to use an existing provisioned service? - at this point, you'll be asked to select the service - choose the database service you've just created. Also, note the URL at which your Etherpad-Lite installation will be available.
If all went well, you should now be able to point your browser to the url of your new Etherpad and start a new pad. Enjoy!

The --runtime node06 option is currently necessary, since vmc does not properly recognize needed version of node. If omitted, a 0.4.* version would be used by default, which does not work with current Etherpad-Lite due to missing zlib dependency.
One can also skip creating a mysql service before pushing, and create it when prompted by the push command.
